Description of the Related Art

As the value and use of information continues to increase, individualsand businesses seek additional ways to process and store information.One option available to users is information handling systems. Aninformation handling system generally processes, compiles, stores,and/or communicates information or data for business, personal, or otherpurposes thereby allowing users to take advantage of the value of theinformation. Because technology and information handling needs andrequirements vary between different users or applications, informationhandling systems may also vary regarding what information is handled,how the information is handled, how much information is processed,stored, or communicated, and how quickly and efficiently the informationmay be processed, stored, or communicated. The variations in informationhandling systems allow for information handling systems to be general orconfigured for a specific user or specific use such as financialtransaction processing, airline reservations, enterprise data storage,or global communications. In addition, information handling systems mayinclude a variety of hardware and software components that may beconfigured to process, store, and communicate information and mayinclude one or more computer systems, data storage systems, andnetworking systems.

DETAILED DESCRIPTION

In the following description, details are set forth by way of example tofacilitate discussion of the disclosed subject matter. It should beapparent to a person of ordinary skill in the field, however, that thedisclosed embodiments are examples and not exhaustive of all possibleembodiments.

As used herein, a reference numeral refers to a class or type of entity,and any letter following such reference numeral refers to a specificinstance of a particular entity of that class or type. Thus, forexample, a hypothetical entity referenced by ‘ 12A’ may refer to aparticular instance of a particular class/type, and the reference ‘12’may refer to a collection of instances belonging to that particularclass/type or any one instance of that class/type in general.

In one or more embodiments, power may be provided across a hinge of aninformation handling system that includes one or more displays. Forexample, power may be provided across a hinge that couples two displaysof the information handling system. In one or more embodiments, inputvoltage from a power supply to the information handling system may vary.For example, the input voltages may include five volts (5V), twelvevolts (12V), and twenty volts (20V), among others. For instance, theinput voltages may be direct current (DC). In one or more embodiments,input power may be received by the information handling system via aport included in a chassis of the information handling system. In oneexample, input power may be received by the information handling systemvia a first port included in a first chassis of the information handlingsystem. For instance, the first chassis may include a display. Inanother example, input power may be received by the information handlingsystem via a second port included in a second chassis of the informationhandling system. For instance, the second chassis may include a seconddisplay.

In one or more embodiments, the information handling system maydistribute power to its components at one or more voltages. In oneexample, a backlight driver of a display of the information handlingsystem may utilize a higher voltage than a processor of the informationhandling system. In another example, the backlight driver may utilize ahigher voltage than a voltage provided by an external power supply orprovided by an internal power supply. In one or more embodiments, one ormore components of the information handling system may dynamicallyprovide power at one or more voltages based at least on one or morevoltages provided by an external power supply and/or provided by aninternal power supply.

In one or more embodiments, an internal power supply may include abattery. In one or more embodiments, a chassis of the informationhandling system may include an internal power supply.

In one or moreembodiments, the first chassis of the information handling system mayinclude a first portion of components of the information handlingsystem, and the second chassis of the information handling system mayinclude a second portion of components of the information handlingsystem. In one example, power may be transmitted from the first chassisto the second chassis. In a second example, power may be transmittedfrom the second chassis to the first chassis. In a third example, powermay be received by the first chassis from the second chassis. In anotherexample, power may be received by the second chassis from the firstchassis.

In one or more embodiments, power at a first voltage, DC, may beincreased to a second voltage, DC, before providing the power to achassis. In one example, providing the power at the second voltage,greater than the first voltage, may reduce power loss in powertransmission. For instance, providing the power at the second voltage,greater than the first voltage, may reduce an amount of current toprovide the power or to provide an amount of power slightly less thanthe power. In another example, providing the power at the secondvoltage, greater than the first voltage, may reduce an amount ofconductor material to transmit power. For instance, reducing an amountof conductor material to transmit power may provide one or moreenvironmental benefits. In one or more embodiments, power at the secondvoltage may be decreased to the first voltage after receiving the powerfrom a chassis. For example, decreasing the power from the secondvoltage to the first voltage may include increasing a current. Forinstance, a power value may be a voltage value multiplied a currentvalue.
